Rey Mysterio has announced Monday on Twitter that he will be undergoing surgery this Friday after underneath an injury to his knee. 


The masked player blew his knee, supposed to be his ACL, while attempting a baseball slide during his match against Alberto Del Rio on last week's episode of Raw. 

There is talk that he may not be able to come back to action until Wrestle Mania XXIII.

The WWE crew member that Kevin Nash shook hands with offstage on RAW as he was walking down the hallway was Cal Cole, son of WWE broadcaster Michael Cole.
